burner ignites for approx 30secs then fails and reset light and burner light flashes. resetting produces same as above. leaveing it as above the burner will ignite after 5/8 mins and then fails as above
have the same prob. new fan & new pcb still same. lights almost but not quite alternate, this signifies blockage apparantly. Pump is ok. The same happens whether its hot water or heating, any ideas???

sounds like its overheating then shutting down, is the pump working?
